Is someone getting a valid build for USE_GRAPHICS=1 ?

mine is lost in reset loops...

Did you try to change number of vars ?
For the case that we have an heap overflow because of graphics

in file ESP8266_BOARD.py ?

That's the only place I know, but I'm not an expert.
As far as I understand the py file is used during make to create some sources in /gen

Yes - the py file determines how much RAM gets used for variables - be sure to make clean though - just in case :)

@tve I was trying to think of why all the RAM would disappear when the graphics library got included. It'll be the bitmap and vector fonts - specifically:

• https://github.com/espruino/Espruino/blob/master/libs/graphics/bitmap_font_3x5.c
• https://github.com/espruino/Espruino/blob/master/libs/graphics/vector_font.h

Could we maybe have a READ_CONST_UINT8 macro that we can use when accessing data that we think might be in flash memory? On ARM it could default to a normal access, but on ESP8266 it could load 32 bits and shift to get the right byte.

It'd simplify the whole memoryArea thing too.

peek8 and peek16, both are not running on flash for ESP8266
peek32 works fine
Would we need a solution for both cases ?

I suppose so - we'd need READ_CONST_UINT8 and READ_CONST_UINT16.
